You can use too this trick on Ubuntu :D
Another possibility is to modify the file /etc/sudoers :
[code]sudo vi /etc/sudoers[/code]

Ps : visudo is better, safer to use because : [quote]visudo edits the sudoers file in a safe fashion, analogous to vipw(8). visudo locks the sudoers file against multiple simultaneous edits,
provides basic sanity checks, and checks for parse errors.[/quote]

What if I were to download a malicious script that asked for sudo…I would never know, right?

If I never did this "trick" I may have seen the password prompt and thought twice about it.

I think if a user is "smart" enough to know what is a potential threat to security on a unix / linux system, then they are "smart" enough to know how to do this "trick" already. This how-to is geared toward newer users then who wouldn’t know any better.

But hey, I guess if you use the package manager and official repos only then whats the difference?

I agree with you that for security reasons is not advised to disable sudo password. [b]SO, MY ADVICE FOR EVERYBODY IS: IF SECURITY CONCERN YOU, DON`T DO IT :)[/b]
